To all 'whom t may concern:

Be it known that I, THouAs H. KANE, a citizen of the United States, andresiding at Youngstown, in the county of Mahoning and State of Ohio,have invented a new and Improved Ceiling, of which the following is aspecification.

The present invention relates to a ceiling particularly suitable forportable or temporary hospitals and schools, election booths, garagesand the like, and its object, briefly stated, is to provide very cheaplya construction that possesses, in greater measure than structuresheretofore known, lightness, strength, ease of manufacture and erection,and general capacity for service.

This application is a division 'of my application for patent on buildingconstruction, Serial Number 69,330, filed December 30,1915.

The nature of the invention will be more fully understood by referenceto the specification and drawings, in the latter of which Figure 1 is afragmentary transverse vertical section through a building to which theceiling is applied and Fig. 2 is a fragmentary central longitudinalsection corresponding thereto. Fig. 3 is a similar section showingapanel which is not provl'led with a door, the ceiling also beingomitted. Fig. 4 is an end view. Fig. 5 is a diagrammatic fragmentaryhorizontal section or truss and panel diagram. Fig. 6 is a fragmentarysection on either of the lines 6-6 or GSL-6 of Fig. 1. Fig. 7 is afragmentary vertical section showing a modified construction.

1n the embodiment of the invention shown, the external wall surface isformed of corner panels 1, side panels 2 and 3, end panels l and doors6, gable ends 8 and filler plates 9 above the doors-all of thin sheetmetal. Each of the panels 1234 has its side edges bent inwardly to formflanges 13 grooved at 14, and adjacent panels 1-2- 3-4 are joinedthroughout a portion of their height by thin metal posts or key plates15, having ribs 16 received in the grooves 11 By perforating the fianges13 and the posts and providing slotted bolts 18 and wedges 19, a veryconvenient means is afforded for tightly together to exclamping theparts clude dust and air. These elements, while preferable, may bereplaced by wall structures of widely different character.

Resting directly on the upper ends of the members of each pair of postsare gusset plates 21 having ribs 22 (Fig. 1) conforming to and inalinement with the ribs on the posts, and to these gusset plates arejoined sheet metal rafters (each of which may include an upper fiange23, a web 2st and a lower fiange 25) and sheet metal ties 26, preferablyof channel'cross-section. Sheet metal channel Suspenders or intermediatemembers E28 are used to join the peaks of the rafters to an intermediatepoint of va corresponding tie. The various joints between the gussetsand Suspenders and the rafters and tie are preferably formed by spotwelding; and, in order to provide a large surface of contact, the iangesQ5, together with the flanges of the suspenders, are bent out into theplane of the web of the corresponding member as indicated respectivelyat 30 and 31 (Figs. 1 and E2). The members 23-24-25 and ZG constitute,respectively, the compression and tension chords of the roof truss.v Ifdesired, the peaks and ties of adjacent trusses may be connected bysheet metal sway braces 32 also welded in place (Fig. The gussetspreferably include outwardly projecting eave supporting extensions 33(Fig. 1).

1t will be observed that the posts of key plates 15 terminate somedistance below the roof and that the panels 1--2-8 extend upwardlythereto and are each provided with a flange 34 that lies substantiallyin the plane of the upper faces of the rafters. (Fig. 1.) When thegussets are in position and the plates are joined thereto by wedge bolts18-19, as heretofore explained, a tight lweatherproof joint is thereforesecured throughout the height of the side wall.

The end panels differ from the panels 2, merely in that they have theirupper edges bent to form a horizontal flange 36 (Fig. 2), grooved toconform to a ribbed horizontal bar 38, that extends across the buildingand is of the same cross-section as the posts, except that its edge 39(which projects outwardly) is bent to form an inclined drip board. Thesheet metal end gables are zontal flange 4l conforming to the ribbedupfper surface of the bar 38 'and also havin ange 42 bent into the planeof the roo Similar flanges (not shown) along the adjacent ed s of thehalves inclose a vertical stiffening ar 44 (Fig. 3) of the samecrosssection las the join the several parts as before. Projectingoutwardly from the flanges 42 and preferably welded thereto (Fig. 2) areflat metal light-sealing lates 45, not shown in Fig. 3.

The filler p ate 9 (Fig. 2) has ribbed horizontal flanges 46 and 48 thatconform respectively to the ribbed surfaces of the bar 38 and the lintelbar 49, the edges ofthe latter of which project beyond the flange 48. Anupper sheet metal jamb plate 50 including edge flanges 5l and a stopportion 52 is detachabl secured to the bar 49 by bolts 53. As the partsare clamped together by wedge bolts 18-19, the lintel bar and the jointplate may be said to b e sus ended from the bar 38. The depth of the pl)as to bring the upper edge of the door 6 below the eaves, from which itfollows that the door may be readily inserted in lieu of one of thepanels 2 or 3, they being of the same width; As indicated at the rightside of Fig. 7, a wooden lintel bar 54 may be substituted for the metallintel bar and jamb;

1t is preferred to'provide -a rib 55 to insure a tight joint when thescrews 56 are entered.

The ceilings are formed by sup orting a series of asbestos or otherboards 2 on the lower flanges of the ties 26 and on sheet l metal angleirons 73 or plates 75 welded, re-

spectively, to the webs and lower flanges of the ties. At the ends ofthe building the ceiling plates maybe supported on sheet metal hangerplates 76 that lie flat against lining boards 65 (which may be used tosecure dead air spaces) and by the lintel structure. It is obvious thathanger plates, simlar to the plates 76, may be used between the sides-ofthe door and the corners of the building.
